To all whom it may concern:

The invention relates to weighing appliances of the kind indicating wci or the load by the movement oi a pointer ov r owing the use of standard weights and fractional or precision weigher such as a spring or pendulum balance.

The invention is comprised in the hereinits object being to produce a some we I ing appliance very much snore accurate both in Weighing and in its indications, and much less liable to derangement consequent upon the wear of parts. A weighing machine or this kind has two systems olt' wcighing operating in combination, the one system providing for the use on the weight receiving portion of the beam, or balance, of standard weights,

or proportional weights if the beam or balance is unequally armed as in the case of a compound lever weighing machine, and the other system providing for the use of spring or pendulum balan :e used only as a fractional weigher additional to the standard weights or proportional weights whicl'i are used in th machine to weigh the part of the load.

The invention provides in combination with the two systems aforesaid. an addition-al spring; or pendulum balance or other resistant automatically operative througl out the entire range of the machine as s rough weighing mechanisnn lrom the scent of the scale pan or platiorru, to select the standard weights or proportional wei hts when the load is suilicient to need same, and v tion, Whenthe load is'placed upon the scale Specification of Letters iurent.

Simultaneously with the selection or rejection of the standard Weights and the lowering of the scale pan or platform, an indicator is moved to view at a window into a position proportional to the standard Y-79/l; 1't 3 s ected rejected, and in combination with same further indicator, moved only by the fractional weigher, operates to show fractional weighings.

A similar anchorii'ig rod is uscd l'oii the same purpose in respect of the standard weight receiver, j, to insure its movement being always; truly vertical.

The ratchet toothed sector 9 carries a movable spring controlled stud g" which is operiitivel common to u number of bellci'anlr levers 71- suitzibly iuloriuncd at h to the casing of the machine, said stud being norn'uilly held clear of said levers h by its spring. the machine is designed to weigh up to sixteen pounds, and the aggregate standard Weights used in the machine total fifteen pounds, there are fifteen of such levers controlling the four standard weights and the combinations to be obtained from thcm, leaving always the fractional weighing, anywhere Within and up to sixteen ounces, to be effected by the fractional Weighing uicchanism, to be hereinntter described. The weights f P, f and f are each normally poised by a lever 2', so as to exert" no influence upon-the iveight receiver ruined at 2' within the czasmgnnd 1S opt l upon by [L spriu r a which is accurately teue'toned or powere to ust 31-0193 the weight. The upper three of such lovers are broken en ity in Fig. 1. For

Such a lifter rod is; shown separately in Fig. 14-, and by a modification in. construction only in Fig. 15, and it will be seen toot, each rigidly carries a: number of pegs j" to operate against tlie'lm-ersuz' and also against :2, number of smaller lcvcre's, is, liilcrumed to the casing at 5: for loci lifter rod HllUWn in F i. i of the one 1 he carries nine each bell-crank rod, WOI'l-I ill 2 Q When this oemculei :rod is lifted. by its hellcrank lever, it first; rocks all the locking levers out of hheir opemiive posisia'ms, as shown, co inoperative positions, {one is shown in lines iohig. 1), so that iihe foot levers a: may he afterward rocked, hy lhe continued upward movement of ehe liffhe-zoei, to life all four stenclei'd. weights f i aml i clear of their rests or supports on the weight receiver f.

Each lifter rod 3' moves ver'tically through a clearance hole in a plotolilce par l, which forms a portion of each lever i, and against the undei side of which the pegs of the lifter rod operate, 1nd against the top siele of which the locking lever is operates.

manner, dependent upon the substance or article to be weighed.

In order to prevent fraud and make it impossible for the weighing machine to ishow at the windows a weight indication greater than that corresponding to tlie load, a very delicately poised shutter may be provided to close the windows under certa n conditions. The shutter normally tenc to nncover the windows, but is held from doing so by two stops, or equivalents, one oi which is automatically moved when the standard weights are selected by placing the load on the platform, and the other of which is re moved precisely at the actual weighing, so that the windows are not uncovered until the actual weighing is complete. new, even while the sector 9/ is locired, a portion of the load is taken off to leave said load less in weight'thanihe standard weights used, the natural. lifting of the platform the main beam will automatically operate the shutter to close the-windows and read, if desired, VV'eigh again or Incorrect weight? A diagram of'this shutter niechanisn'i is represented by Fig. 16, wherein y indicates due of the windows shown in Figs. 1 and 2, and a shutter opening and closing same. The knife-edge pivotiof the shutter 13 at 3 to bear on the casing, and 9 is a weighted arm rigidly attached to the shutter. y is 'the one stop, and y is the other stop, the first named stop in theform of a rod, and the second stop in the form of a lever worked by the rod 9". The rod 3, is connected to the hand operated mechanism for locking the selecting mechanism and bring ing the standard weights into use, and the stop y is connected to the scale pan or pla form. The shutter 3 may bear the words Weigh again or Incorrect weight i and normally, by the weighted arm takes tip a position opening the windows.
